Camponotus gambeyi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: New Caledonia, a tropical island in the South Pacific. Found in dense humid forest on ultrabasic rocks ^[1]. This is a native species, not invasive.
• Colony Type: Unknown, colony structure has not been specifically studied for this species.
• Size & Growth:
  • Queen: Size data unavailable, no measurements exist for this species
  • Worker: Size data unavailable, no measurements exist for this species
  • Colony: Unknown, no specific data for this species
  • Growth: Unknown, specific growth rate has not been documented
  • Development: Unknown, no species-specific development data available (Development time is unconfirmed for this species)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Being from tropical New Caledonia, they need warm conditions year-round.
  • Humidity: High humidity required, they naturally live in humid forest environments. Keep nest substrate consistently moist but not waterlogged.
  • Diapause: No, being from a tropical island, they do not require hibernation. Keep temperatures stable year-round.
  • Nesting: In nature, they likely nest in rotting wood or under stones in forest habitats. In captivity, a Y-tong (AAC) nest or plaster nest works well. They prefer tight, dark chambers.
• Behavior: Generally calm temperament typical of carpenter ants. They are not particularly aggressive but will defend their nest if threatened. Workers are moderately active foragers. Escape prevention should be moderate, they are not tiny ants but can squeeze through small gaps.
• Common Issues: high humidity maintenance is critical, dry conditions will stress and kill colonies, tropical species cannot tolerate cool temperatures, keep above 24°C, limited availability as a species, may be difficult to find in the antkeeping trade, wild-caught colonies may carry parasites specific to their native range, lack of species-specific care data means keepers must rely on genus-level guidance

Natural History and Distribution

Camponotus gambeyi is endemic to New Caledonia, a unique tropical island in the South Pacific known for its distinctive flora and fauna. The species was first described by Carlo Emery in 1883 and has been recorded from various locations across the main island ^[2]. It belongs to the subgenus Tanaemyrmex, a group of carpenter ants. The species is found specifically in dense humid forests growing on ultrabasic rocks, a geological formation common in New Caledonia that creates unique soil conditions ^[1]. This habitat specialization suggests the species prefers stable, humid microclimates with plenty of cover and organic material.

Nest Preferences and Housing

In their natural habitat, C. gambeyi likely nests in rotting wood or under stones in the humid forest floor, similar to other Camponotus species. For captive care, a Y-tong (AAC) nest or plaster formicarium works well. They prefer tight, dark chambers that mimic the inside of a rotting log or underground cavity. The nest should have a water reservoir to maintain humidity, these ants are sensitive to drying out. Keep the outworld simple with a foraging area and provide a hydration station.

Feeding and Diet

Like most Camponotus species, C. gambeyi is omnivorous with a preference for sugary substances and protein. In captivity, offer sugar water or honey regularly as a constant energy source. For protein, provide insects such as mealworms, crickets, or other small arthropods. They likely tend aphids in nature for honeydew, so offering sugar water is a good substitute. Feed protein prey 2-3 times per week, and keep sugar available at all times. Remove uneaten prey after 24 hours to prevent mold issues in the humid setup they require.

Temperature and Humidity Requirements

Being from tropical New Caledonia, these ants require warm and humid conditions year-round. Maintain temperatures between 24-28°C in the nest area. A heating cable placed on top of the nest can help maintain stable temperatures, especially in cooler rooms. Humidity should be kept high, the forest floor environment they inhabit is consistently moist. Keep the nest substrate damp but not waterlogged, and provide a water gradient so workers can choose their preferred moisture level. Avoid placing the colony in air-conditioned rooms or anywhere temperatures might drop below 22°C. ^[1]

Colony Development

Queen founding behavior is unconfirmed for this species. The first workers, called nanitics, are typically smaller than mature workers. After the first workers eclose, the colony enters a growth phase. Specific development time and growth rates are unknown for this species, keepers should monitor their colony's development and adjust care accordingly.

Behavior and Temperament

Camponotus gambeyi has a temperament typical of carpenter ants, generally calm and not overly aggressive. Workers will forage actively in the outworld and are capable of carrying relatively large prey items compared to their body size. They do not have a functional sting but may bite if threatened, as Formicinae, they can spray formic acid from their acidopore as a defense mechanism. The species is moderately active and workers will establish clear foraging trails when food is available. Escape risk is moderate, while not tiny, they can squeeze through small gaps, so standard escape prevention measures are sufficient.
